Definitions

  • the present invention relates to the technical field of continuous casting.
  • liquid metal e.g. Steel
  • cast to an at least partially solidified strand which is continuously drawn out of the continuous casting mold and supported in the subsequent strand guide of the continuous casting machine, guided and cooled further.
  • the invention relates to a continuous casting mold with at least one temperature sensor, comprising a copper plate having a groove with a groove bottom, an optical waveguide as a temperature sensor extending in a cannula, and a filler material which closes the groove at least in sections.
  • the temperature sensor can detect events, e.g. on the adhesion of the strand to the mold inner wall, be inferred inside the continuous casting mold.
  • simply the temperature of the mold itself can be measured.
  • the invention relates to a production method for the continuous casting mold with the temperature sensor.
  • the continuous casting mold has a plurality of so-called thermocouples, wherein the temperature distribution via thermoelectric voltage change of the thermocouples can be measured in the mold.
  • thermocouples have been proven in practice, many thermocouples are needed to detect a spatially relatively precisely discretized temperature distribution in the mold, resulting in a high cabling effort.
  • thermocouples are sensitive to electromagnetic fields, as they occur, for example, in agitators for molds.
  • optical fibers typically glass fibers
  • multiple fiber Bragg gratings are used instead of thermocouples. This allows the temperature in the mold to be measured at a plurality of measuring points (the locations where the fiber Bragg gratings are located) of the glass fiber at a distance from each other. This reduces the cabling effort.
  • the coefficients C s and C t indicate the dependence on the strain and the temperature, cf. http://en.wikipedia.org/wiki/Fiber Bragg grating).
  • optical waveguides require the best possible thermal connection to the mold.
  • the fibers are mechanically much more sensitive than conventional thermocouples, the fibers must be mechanically protected.
  • the glass fibers are poured directly into the workpiece, for example by the positive pouring of the glass fiber by synthetic resin, polyester or the like. Although this gives a sufficiently high mechanical protection, but the fiber is imposed on the thermal expansion of the surrounding material, which the measured Temperature value falsified and also computationally can not always be completely corrected. In addition, the glass fiber reacts only slowly to temperature changes in the mold.
  • a metal cannula is laid with a glass fiber in a groove or a bore.
  • the fiber is indeed decoupled from the thermal stresses of the workpiece, however, results due to the air gap between the bore or groove and the cannula outer wall poor heat connection, resulting in a highly time-delayed temperature signal.
  • the isotropic thermal conductivity of the metal cannula means that the temperature signal to be measured is falsified and the spatial-temporal resolution suffers (blurred temperature profile over several temperature measuring points).
  • JP H09-47855 is a continuous casting mold with at least one temperature sensor known, comprising a copper plate with a groove and a groove bottom, an optical waveguide as a temperature sensor extending in a cannula, and a filler material which closes the groove at least in sections.
  • a continuous casting mold with at least one temperature sensor known comprising a copper plate which is at least partially penetrated by a bore and an optical waveguide as a temperature sensor which extends in a cannula.
  • a cannula with a glass fiber optical fiber or a portion thereof laid in a groove on the cold side of a continuous casting mold between two graphite films, so that the cannula does not rest on the groove base and then closed the groove with a filler .
  • the foils ensure a good thermal connection of the glass fiber with at the same time very low transmission of thermal stresses of the surrounding material.
  • the filling material closing off the groove provides the necessary mechanical and chemical protection and can be suitably selected for use: criteria include water-tightness, mechanical strength, elasticity with regard to thermal expansions, temperature and corrosion resistance, etc.
  • the hot side ie the side in contact with the liquid metal
  • the hot side facing away from the copper plate, regardless of whether the copper plate made of pure copper or a copper alloy and whether the cold side of the copper plate possibly supported on a support structure (eg the water tank).
  • a tear resistant layer e.g., a textile tape
  • the second heat conducting foil is disposed between the second heat conducting foil and the filling material.
  • thermal conductivity of the tear-resistant layer in the thickness direction ⁇ as the lowest thermal conductivity of the first and second thermally conductive films.
  • thermal conductivity in the thickness direction is z ⁇ as the thermal conductivity in the longitudinal and transverse directions x, y.
  • the filler is a synthetic resin, a plastic such as polyester or PTFE, or a metal.
  • the filling material may e.g. by casting, laminating or joining (e.g., soldering).
  • a Layer of a first thermally conductive foil disposed between the cannula and the inner wall of the bore, so that a high heat flux is ensured from the inner wall of the bore to the outer wall of the cannula.
  • the film completely bridges the gap between the inner wall of the bore and the outer wall of the cannula. In a technically almost equivalent embodiment, however, an (air) gap may remain.
  • thermoelectric voltages are only very slightly transmitted to the glass fiber (this results in a more accurate temperature signal), on the other hand is due to the increased thermal conductivity of the graphite in the direction x, y the film layers ⁇ xy ⁇ 100 W / ( mK ) in comparison to the thickness direction z ⁇ z ⁇ 10 W / ( mK ) given a very good temperature connection, so that compared to conventional only with air filled holes a much more timely and spatially better resolved temperature signal in the fiber sensor arises.
  • the first and / or the second graphite foil has an anisotropic thermal conductivity.
  • a good heat conduction from the bore or the groove to the cannula and the optical waveguide is ensured;
  • an excessively high heat conduction in the longitudinal direction of the bore or the groove is prevented, so that the spatial or temporal resolution does not suffer.
  • the first and / or the second graphite foil consist essentially of graphite or graphene. Films of these materials have a high thermal conductivity in the longitudinal and transverse directions, but a much lower thermal conductivity in the thickness direction of the film.
  • the thickness direction of the first and / or second thermally conductive foil in the longitudinal direction of the groove or the bore extends.
  • the cannula is made of plastic, preferably heavy duty PTFE, glass fiber, fiberglass or a ceramic. All these materials have a much lower thermal conductivity compared to metal, which has a favorable effect on the spatial resolution. The mechanical stability of these materials is also sufficiently high.
  • the optical waveguide has a plurality of temperature measuring points over the longitudinal extent of the optical waveguide, wherein the temperature measuring points are preferably formed as a fiber Bragg grating.
  • the temperatures can also be determined by a measuring system based on the Rayleigh principle.
  • the continuous casting mold with the optical waveguide has an evaluation unit for evaluating the temperature at the temperature measuring points of the optical waveguide, the evaluation unit being connected to the optical waveguide.
  • a graphite foil has the highest thermal conductivity in its longitudinal and transverse directions.
  • a rigid cannula preferably a metal or plastic cannula occurs.
  • the piercing can be done by another impact tool.
  • the heat flow in the radial direction is maximum and minimal in the axial direction.
  • the FIG. 1 shows a continuous casting mold 1 with a hot side 3 and a cold side 2 of the DE 10 2009 060548 A1 ,
  • an optical waveguide 8 is inserted into the groove base 4a of a groove 4 as a temperature sensor 7.
  • the optical waveguide 8 has a plurality of temperature measuring points indicated by X in the figure. As the optical waveguide 8 is secured in the groove 4 and protected from mechanical damage is open.
  • the Fig. 2 shows a first variant of a copper plate 13 of a continuous casting mold with a groove 4, in which a glass fiber optical waveguide 8, which runs in a cannula 12 (eg. From the plastic PTFE) has been inserted.
  • The, for example produced by milling or erosion, groove 4 is disposed on the cold side 2 of the copper plate 13.
  • the cannula 12 is embedded between a first thermally conductive foil 5, which rests on the groove base 4 a, and a second thermally conductive foil 6.
  • the two heat-conducting foils 5, 6 are each aligned such that the thickness direction z of the foils runs in the depth direction t of the groove 4.
  • the longitudinal, transverse and thickness directions x, y, z of the films form a Cartesian coordinate system.
  • the two films 5, 6 are made of graphite, wherein the graphite films in the longitudinal and transverse directions x, y have a thermal conductivity of about 100 W / (mK) and in the thickness direction z a thermal conductivity of about 10 W / (mK).
  • the groove is completely filled by a filler 9, for example. From synthetic resin.
  • the cannula 12 is fully embedded in its longitudinal direction between the first and second thermally conductive sheets 5, 6. alternative For this purpose, it would also be possible to embed the cannula 12 in sections only in the region of the temperature measuring points X in the heat-conducting foils 5, 6.
  • the longitudinal sections between two adjacent temperature measuring points X could therefore have either an air gap or an insulating material between the groove base 4a and the cannula 12.
  • the Fig. 3 shows a second variant Fig. 2 ,
  • a tear-resistant layer here a fabric tape inserted. Through this layer, the filling material 9 can be removed without injuring the cannula 12 or the glass fiber 8. This is advantageous in a revision or repair of the copper plate.
  • the heat conduction would be at the FIGS. 2 and 3 better to orient the films 5, 6 so that their thickness direction z extends in the longitudinal direction of the groove 4. This would result in a low thermal conductivity in the longitudinal direction of the groove 4 and a high thermal conductivity transverse thereto, ie also in the depth direction t of the groove 4. Since the films have only a small layer thickness 5.6, but this requires a higher manufacturing cost.
  • FIGS. 4 and 5 show the results of two comparative calculations, each with identical initial and boundary conditions, showing the heat transfer from the groove bottom 4a of the groove 4 to the glass fiber 8.
  • the thickness directions z of the first and the second heat-conductive foils 5, 6 extend in the width direction b of the groove 4; in Fig. 5 the thickness directions of the films 5, 6 are aligned in the depth direction t of the groove 4. It turns out that although the thermally conductive foils 5, 6 of the Fig. 4 are substantially thicker than the films 5, 6 of the Fig. 5 and in Fig. 5 the cannula 12 rests directly on the groove base 4a - the glass fiber 8 of the Fig.
  • the Fig. 6 shows the cold side 2 of a copper plate 13 in an oblique angle.
  • a cooling medium here water
  • the groove 4 can also be laid meandering to capture by a glass fiber, which is inserted into the groove, not only the temperature in a horizon, but in several horizons, the mold.
  • the Fig. 7 shows a section through a copper plate 13 with a groove 4, in which a glass fiber optic cable 8 is inserted.
  • the arrangement of the filling material 9, the cannula 12, the glass fiber 8 and the first and second thermally conductive foils 5,6 and their orientation corresponds to the Fig. 4 ,
  • the cannula 12 is inserted between a first thermally conductive foil 5 and a second thermally conductive foil 6 so that the thickness direction z of the two heat-conducting foils 5, 6 is normal to the longitudinal direction of the cannula 12.
  • the thermally conductive foils 5, 6 embedding the cannula 12 are inserted into the groove base 4a of the groove 4, so that the longitudinal direction x of the thermally conductive foils 5, 6 extends in the depth direction t of the groove 4.
  • the groove 4 is closed by a filling material 9, so that the filling material 9, the groove 4 at least partially, preferably completely, closes.
  • FIGS. 8 and 9 Two variants for laying a glass fiber optical waveguide 8 in a bore 11 through a copper plate 13 of a continuous casting mold are shown.
  • a metal cannula 12 is retracted with the glass fiber 8 in the bore 11, wherein - to the best possible heat transfer to allow the glass fiber 8 - the radial gap between the bore 11 and the cannula 12 is as narrow as possible.
  • layers of a first thermally conductive foil 5 is inserted between the bore 11 and the cannula, the thickness direction z of the foils 5 extending in the longitudinal direction of the bore 11.
  • first thermally conductive film could be pushed onto the cannula so that the thickness direction z of the films extends in the longitudinal direction of the cannula.
